When it comes to cloudy days, I feel uncomfortable, hot, bored and sweaty all over. What happened?

Normal drop! Me, too. A lot of people usually do this. As long as you are isolated from this weather, there will be no problem. In short, it is to devote yourself to other things, such as your work, study, games and so on. Then do more refreshing exercises and don't let yourself die in this weather. Then protect your body. This kind of weather is prone to rheumatism and the like, so we should prevent it early, and people of our physique are prone to hidden dangers.
